Figure My improvements co priseh Oa Y p s 0 55 outer ends of the crank members on the tracks 23 and 24;a pair of operating levers H--l-I operatively connected to the bars C-C;link members KK connecting the levers H H to the bars D -D; combinedsupporting and guide brackets M,M; and links N-N supporting the leversH-Hfrom the brackets M- lvi.

The four crank members AA-AA are arranged in pairs at opposite sides ofthe door 22, the members of each'pair being disposed respectively at thetop and bottom of the door. crank members serve to support theidoor 22on the tracks 23 and 24 and are rotatably mounted in the'bearingbrackets BIB and BB which are fixed to the door; The bearing brackets BBand BB are arranged in pairs at opposite sides of the door, the membersofeach pair being disposed in vertical alignment closely adjacent, tothe top and bottom edges of the door. Each bracket B comprises a base orback plate 28 and a cover plate 29 overlying the back plate and securedto the outer face, of the door by bolts or similar securing elements.The back and cover plates are provided with complementary part bearingopenings which together form a vertically disposed, susbtantiallycylindrical bearing opening 39. i

Each crank member A has a substantially cylindrical shaftlike bearingportion 3! journaled in the bearing opening 36 of the correspondingbracket B. At the inner end, the cylindrical bearing portion of thecrank member A is provided with an annular flange 32.which hasshouldered engagement with the inner end of the bearing bracket. portion3| is laterally enlarged, as indicated at 33, said enlarged portionhaving shouldered engagement with the outer end of the bearing bracketB. As-will be evident, the crank mem-' bers A-AAA are thus held againstendwise movement in the bearing brackets BB and BB. At the enlargedouter end 33 of the sleeve section 32, each crank member is providedwith a laterally, outwardly projecting, downwardly inclined arm 35 whichhas a pivot or crank pin 35 at the outer end thereof. The crank pins 35of the arms 34 of the top crank members AA are journaled in the carriersF-'F which are in the form of discs or rollers guided in thechannelshaped opening of the top rail 23 The crank pins 35-35 of thearms 34-34 of .the bottom crank members AA are journaled inthe carriersG-G which are in the form of slides mounted on the track 24. Eachslide'G- has a pair of antifriction rollers 36-36 rotatably mountedthereon at opposite ends, which ride on the top edge of the rail 25 ofthe track 2Q. Each carrier or slide G is preferably provided withdepending spaced side portions 37-31 which embrace the rail of the trackat opposite sides to thereby guide the slide lengthwiseon said track.Between'its ends each carrier G is provided with an upwardly openingbearing seat 38 in Which the pivot or journal pin 35' of thecorresponding lower crank member A is journaled. It will be evident thatThese At the outer end, the cylindrical sleeve the four crank membersare thus swingingly supported from the tracks andcarry and guide thedoor 22 for movement into'and out of the door "opening2l.

, with oppositely disposed, laterally projecting,

transversely aligned, keeper engaging lugs Gil-40.

'The keeper engaging lugs idm are preferably of cylindrical crosssection. Each keeper engaging bar is thus provided with a. substantiallyT- shaped keeper engaging end. The bars C and D of each pair areverticaly aligned and are slidable respectively. in vertically aligned,axial bearing openings 4ldl, of square cross section, of the top andbottom crank members A A at the correspondingsideof the, door. The topbars CC,

'as clearly shown in Figure 1, are longer than the .bottom'bars D--D andhave their lower ends guided in thebrackets M-M, as hereinafter morefully described. 7 V

Although thesliding fit betwen the bars C and D and the square openingsll- 5! of the corres'ponding crank members A--A provides for rotation ofthe crank members by the bars, the fit is rather-looseso as to provide asufficient amount of clearance to permit slight turning of the bars Withrespect to the crank members-to, allow for slight relative adjustment ofthe parts to compensate for the necessary relative movement of the.keeper engaging locking bars and crank members A--A as hereinafterpointed out.

When the door 22 is seated in closed'position within the door opening 21the keeper engaging bars C and D and C and D are Withdrawn to theirinnermost position and in order to accommodate the T-headed keeperengaging portions thereof in that position, the innerends of the arms3535' of the crank members A-A are recessed or pocketed, as indicated at@242.

The operating levers H-H are respectively as- 'sociated with the two'sets of vertically aligned is pivotally connected at its inner end tothe 1 lower end of the bar C, as indicated at 43. Inwardly of thepivoted end 43, the lever H is provided with a laterally offset,outstanding portion 44 formed integral therewith. The lever is supportedfor pivotal movement by the link N which is carriedlby the bracket M andhas its lower end pivotally connected to the offset portion 44 of thelever H, as indicated at $5, thereby supporting the lever for swingingpivotal movement. The lever H is also connected to the inner end of thebar D by a link K having its lower end pivotally connected to the innerend of the bar D, as indicated at 46, and having its upper end Thesupporting bracketsMM of the bars 7 CC' are fixed to the outer face ofthe-door and each bracket M is in vertical alignment with the top andbottom bearing brackets .B.B at the corresponding side of the door. Eachbracket M1 is of two partconstruction comprising a base or back platesection 48, abutting the outer face of the door, and a cover platesection 49 overlying the base section and bolted to the door. The baseand cover plate sections are provided with complementary bearing seatsproviding a substantially cylindrical bearing opening 50 having anenlarged central section 5,! in the form of an annular groove. A bearingsleeve 52 is rotatably mounted in the bearing opening 50 of each bracketM, the bearing sleeve having an enlarged central section in the form ofan annular rib fitting the groove 5| of the opening 50, thereby holdingthe sleeve against endwise movement in the bearing bracket. The bearingsleeve 52 isrotatable in the bearing bracket M and has an outstandinglug 53 thereon to 'whichthe upper end of the 7 as indicated at 55, toaccommodate the lug 53 for swinging movement with the sleeve 52 aboutthe vertical axis of said sleeve. The sleeve 52 serves as a guide forthe lower end of the corresponding bar C and is provided with an axial,vertical guide opening of substantially square cross section withinwhich said bar slidingly fits. As will be evident, the bars CC and thesleeves 52-52 are thus connected for rotation in unison while said barsare slidable endwise in said sleeves. As will be further evident, eachoperating lever H is operatively connected to the corresponding top barC by the link N, which is pivoted to the sleeve 52, and to thecorresponding bottom bar D by the link K, so that swinging movement ofthe lever in a horizontal plane about the vertical axes of said barseifects rotation of the latter and the connected crank members AA, andso that swinging movement of the lever in a vertical plane on its pivot45 forces the bars C and D of each setvertically apart and projects thesame outwardly of the bearing brackets BB to cooperate with thecorresponding keepers E-E.

The keepers EE and EE are arranged in sets at opposite sides of the dooropening 2|, the two members of each set being disposed respectivelyabove and below the door opening and secured to the side wall of thecar. Each keeper E is in the form of a casting having laterally spaced,outstanding wing portions 5656 provided with transversely aligned,opposed, interior cam slots 5'i51 adapted to slidingly accommodate thelugs 4040 of the corresponding keeper engaging bar. The inner endportion of the slot of each keeper, that is, that end portion of theslot which is nearest the door opening, is inclined inwardly toward thewall of the car to provide proper camming action to force the doorclosed or pry the same open when the cooperating keeper engaging bar isactuated. The outer end portions of the slots are substantiallyvertical, as shown, to hold the door locked when the lugs id-40 of thecooperating keeper engaging bar are engaged therein.

The usual locking and sealing latch members 5858 are provided forlocking the actuating lever arms III-I in position when the door isclosed. Locking means in the form of supporting hook brackets 59-59 arepreferably also provided for latching the handle lever arms H--H inposition when the door is completely withdrawn from the door opening oris in position to be moved along the tracks. I

Although the keeper engaging bars C-D and CD are herein disclosed, as ofsquare, transverse cross section and the shaftlike cylindrical bearingportions 3i--3l and 3l--3I of the crank members AA and AA as havingsquare openings in which said bars are engaged to effect rotation of thecrank members by the bars, these parts necessarily need not be so formedto eiTect rotation of the members AA with the bars C and D, inasmuch asthe T-headed keeper engaging ends of said bars, when Withdrawn from thekeepers E-E and E-E and seated in the pockets 4242 and 42-42 of themembers AA and AA lock said members to the bars CD and -D for rotationtherewith. The locking bars CD and CD may thus be formed of round crosssection and the openings of the cylindrical bearing portions or shaftsof. the crank members in which the bars slide may also be of circularcross section without in any way interfering with the proper operationof the mechanism. 7

The operation of my improved door mechanism, assuming that the door isin the closed position shown in Figures 1, 2, 3, 4, and 5, is asfollows: After unlocking the latch members 58- 58 in the usual way, eachoperating lever H is swung outwardly and upwardly from the pendantposition shown in Figures 1 to inclusive to a substantially horizontalposition, thereby moving the parts to the position shown in Figures 6,7, and 8. As will be evident, the levers III-I may be operated either.simultaneously or successively. During the time that the lever H of eachset of keeper engaging bars CD is swung upwardly from the pendant to thehorizontal position, the

inner end portion of the lever swings on the pivot.

45 at the lower end of the link N which is anchored against verticaldisplacement by its connection with the bearing sleeve 52 carried by thebracket M. As the lever H swings on the pivot 45, the top. and bottombars C and D will be pulled inwardly toward each other by the pivotalconnection 43 of the bar C with the lever H and the link connection K ofthe lever with the bar D. The keeper engaging T-headed end of the bar Cis thus moved downwardly while the T- headed end of the bar D is movedupwardly. Inasmuch as the keeper engaging lugs 49 l l of these barstravel respectively downwardly and upwardly in the slots of the top andbottom keepers EE, the door 22 is cammed or pried outwardly from theposition shown in Figure 5 to that shown in Figure 7. When the operatinghandle lever H reaches a substantially horizontal position, the keeperengaging T-headed ends of the bars C and D are completely withdrawn fromthe keepers E-E and are seated in the pockets 42 of the arms 3434' ofthe crank members AA. During outward movement of the door 22 from theposition in Figures 1 to 5 inclusive to that shown in Figures 6, '7, and8, there is necessarily a corresponding slight outward swinging movementof the arms of the crank members AA. The looseness or clearance betweenthe square bars CD and CD and the openings of square cross section inthe cylindrical bearing portions 3 I -3l of the crank members AA permitsof the required slight amount of rotation of the arms of the crankmembers without binding action of the parts.

When the door has been freed from they door opening, as shown in Figures6, '7, and 3, each operating handle lever H is rotated through an angleof 90, thereby rotating the corresponding bars C and D and the crankmembers AA connected thereto from the position shown in Figures 6, 7,and 8 to the positions shown in Figures 9, 10, and 11. As will beevident upon reference to Figure '1, the operating lever H and the crankmembers A-A at the left hand side of the door will be rotated in adirection reverse to the corresponding parts at the right hand side ofsaid door. 7

The door 22 is thus moved out of the door opening 2| clear of the sidewall of the car so that the.

door may be slid along the tracks 23 and 24 to entirely clear the dooropening. In order to prevent accidental movement of the crank arms ofthe crank members A-A and consequent displacement of the door inwardlyjor outwardly with respect to the tracks, while the door is being slidalong the tracks, the handle levers H H are preferably latched inposition by the latch mem bers 59-59; These latch members may be ofanywell-known character for the purpose, but, as hereinbefore described,are preferably of the hook type. In looking the handle levers H inposition, these levers are swung upwardly to a sufficient extent toclear the hooks of the latch members 59 and are then dropped in back ofthe hook portions of said latch members, as indicated in Figure 9.

In closing the door, the operation is the reverse of that hereinbeforedescribed. The door is slid along the tracks 23 and 24 into position infront of the door opening 2!. The handle levers H H are then disengagedfrom the latch members 59-59 and are swung through arcs of 90, therebyrotating the crank members A-A and AA and moving the door from theposition shown in Figures 9, l0, and 11 to the position'shown in Figures6, '7, and 8. At the end of this part of V V the operation, the leverarms H-H aredisposed in horizontal position, extending outwardly atright angles to the plane of the door. In moving the door 22 from theposition show'n'in Figures 9,10, and 11 to that shown in Figures 6, 7,and 8,

the keeper engaging T-head end portions of the bars C-D and -D arebroughtinto substantial vertical alignment with the entrance openings ofthe slots 'l5l of the keepers E--E'. When the parts are in thisposition, each operating lever 1 7 time in the pendant position shown inFigure l,

are locked and sealed in the usual manner by the latch members 58-53.

I have herein shown and described what I now consider the preferredmanner of carrying out my invention, but the same is merely illustrativeand I contemplate allchanges and modifications that come within thescope of the claims appended hereto. V
